CENTRIFUGAL snrnnn'ron.

Application filed August 6,1923. Serial, No. 656,103.

This invention relates to a centrifugal machine and particularly to an amalgamator and concentrator for removing metal from ore sludge or pulp.

The invention contemplates a centrifugal machine so constructed that the ore pulp may pass through a plurality of amal amator stages if desired and finally be subjected to the action of a concentrator, the prime object being to remove the metal from the sludge and allow the sludge to pass off as waste.

The novel construction of the invention will be apparent by reference to the following description in connection with the accompanying drawings, in which- The figure is a vertical, longitudinal, sectional view through a separator constructed in accordance with my invention.

Referring now to the drawings by numerals of reference:

1 and 2 designate two supports which carry a cross bar 3. a discharge hopper 4 having a flow-off pipe 5. The cross bar 3 is provided with a central or hub portion 6, in which is rigidly fastened an upstanding rod 7 carrying at its upper end aplurality of distributors. The distributor 8 comprises a disk made fast to the rod 7 by the nut 9. The disk has a plurality of radial fins 10 and it is secured to the upstanding tubular portion 11 of a similar disk or distributor 12 alsoprovided with radial fins designated 13. The disk 8 is in the first stage 1% of the separator and the disk 12 is in the. second stage 15 of the separator.

The first stage of the separator comprises an inverted, cup-shaped member having an inlet through a tubular shaft 16 and it is fastened to the second stage by fastening devices 17. Between the first and second stage casings lt and 15 is a wall or bafile 18, having an upstanding tubular portion 19 of less diameter than the disk 8 and beneath it. The tubular portion surrounds the tubular portion 11 and it constitutes an exit from the first stage into the second stage so that material from thefirst stage will drop onto the distributor disk 12.

The bottom 20 of the second stage is provided with an upstanding tubular portion 21 of greater diameter than the tubular The cross bar supports member 22 of the concentrator distributor 23 so that the material may pass from the second stage into theconcentrator casing v toned by the concentrator are all, rigidly supported on the rod 7. The distributo'r'23 for the concentrator is provided with radial fins 27 and the distributor has a depending flange 28 spaced fromthewall of the concentrator 24. The bottom 29 of the'concentrator hasan upstanding tubular portion 30 of greater diameter than the rod 7 so that material may pass from it into the waste pipe '81 carried by the bottom of the hopper 1.

The first and second stages of the amalgamator carry annular mercury columns 32 and 33. Therefore, as material enters the first stage through the hollow shaft 16, it will flow over the edge of the disk 8 and since the outer casings of the three stages rotate in unison (since they are fastened together), the material will come into contact with the mercury in the first'stage so that the mercury can take up some of the metal. The material will then pass into the second stage where any metal which has not been taken out by the first stage will be acted on, and finally, the material will pass into the concentrator where the material will'be subjected to a concentrating action in the usual manner. The concen trates can flow out through the outlet port 34 in the bottom of the concentrator, into the hopper, and then out through the pipe 5.

It will be apparent that the ore sludge will be subjected to a tortuous path through the machine so that there will be ample time for it to be acted upon by the mercury columns and by the concentrator so that practically all of the metal will be taken out.

The hollow shaft 16 maybe the drive shaft and it can be driven by any appropriate means, the distributors in the present machine being stationary so all the rotary motion will be provided by the casing.

The device canbe readily assembled when taken apart fo inspection or repairs and 1t will provide an eflicient means for recovering line metal from ore sludge or pulp. After the machine has been in use, the mercury can be taken out and subjected to the usual process to recover the metal.

WVhat I claim and desire to secure by Letters-Patent is 1. In a machine of the class described, an amalgamator casing aving a vertical axis, a concentrator casing having a vertical axis communicating With the amalgamator casing, the amalgamator casing having an inlet and the concentrator casinghaving an outlet and a flat disk distributor in the respective casings having upstanding radial Wings,

2. In a machine of the class described, an amalgamator casing having an inlet, a concentrator casing communicating with the amalgamator casing and having an outlet, and rigid distributors in the respective casings. v

3. d An amalgan'iator and concentrator comprising a multi-stage amalgamator having a vertical axis,'a concentrator having a vertical axis, the stages of the amalgamator communicating one'ivith the other and the lowermost amalgamator stage communicating \vith the concentrator and distributors in the respective stages of the amalgamator and concentrator, said distributors comprising horizontal, rotatable disks having upstanding radial vanes.

a. In a device of the class described, a plurality of superposed casings, the lower one of which is a concentrator and the upper ones of Which are amalgamator casings, an nular mercury columns in the amalgamator casings, a rigid rod extending concentrically through therespective casings, and distributors rigidly secured to the rod.

5. In a device of th'e class described, a plurality of superposed casings, the lower one of Which is a concentrator and the upper ones of Which are amalgamator casings, annular mercury columns in the amalgamator casings, a rigid rod extending concentrically through the respective casings, and distributors rigidly secured to the rod, the distributor in the amalgamator casing having a depending flange spaced from the Wall of the concentrator.
